Senior Software Engineer - .NET

Here's what makes this role different: you're not just a. NET Engineer who "also knows AI. " We want someone who has already figured out that tools like Cursor, Claude Code, and Codex aren't toys - they're force multipliers. You'll use AI agents every day to tear through migrations, refactors, and test coverage that would take a traditional team weeks. But you also know when the AI is wrong, when to step in, and how to keep quality high. Think of it as having a junior engineer with infinite energy and zero judgment - your job is to supply the judgment.

Responsibilities

• Use AI agents (Cursor, Claude Code, and Codex) to blow through framework upgrades, refactors, API extraction, test scaffolding, and documentation.
• Build reusable playbooks the team can actually follow: prompt templates, repo-level agent instructions, migration checklists, review heuristics, and clear "definition of done" standards for AI-assisted changes.
• Upgrade legacy services to current. NET (LTS where it makes sense), untangling architecture boundaries, and fixing the performance issues.
• Push toward a proper API-layer architecture - RESTful, versioned - built for correctness and maintainability.
• Get involved with SQL servers: query performance, indexing, transactional correctness. Build a data pipeline (Kafka, etc. ) as per needs and requirements.
• Build with security and privacy as defaults, not afterthoughts. Least privilege, safe data handling, the works. This is healthcare - getting it wrong isn't an option.
• Put real quality guardrails in place: automated tests that actually catch things, CI that blocks bad changes, structured logging, and observability that tells you what's happening before users do.
• Review code thoughtfully, have honest architectural conversations, and raise the bar without being a jerk about it.
• Partner with analysts, stakeholders, and other engineers to turn business problems into working software - not just technically correct software, but software that actually solves the problem.
• Help build delivery plans that are honest about trade-offs. "Right" vs. "Right now" is a real tension - you'll help the team navigate it with pragmatic milestones.

Requirements

• 5+ years building and shipping production systems. Not side projects - real software with real users. solving skills; able to work independently and collaboratively in fast-moving teams.
• Some C# and modern. NET experience (Core and beyond). Especially in large codebases, and you've done meaningful refactoring and migration work, not just greenfield.
• Strong SQL Server chops - schema design, query tuning, performance troubleshooting. You've worked on data-heavy applications where the database wasn't an afterthought.
• Cloud experience with Azure and/or AWS. Azure is particularly relevant here.
• API design experience - you've built and maintained service-oriented architectures with real versioning, auth, reliability, and testing practices.
• You actually use AI coding tools as a daily driver. Cursor, Claude Code, Codex, or similar - and not just for autocomplete. You've used agents for multi-file refactors, migrations, test generation, and review workflows.
• You have opinions about what works and what doesn't.
• You communicate clearly. Good PR descriptions, straightforward design docs, pragmatic collaboration, and low ego. We don't need a rockstar - we need someone the team trusts.

Preferred Qualifications

• You've actually done a legacy ASP. NET/. NET Framework modernization before. Bonus points for Azure modernization patterns.
• Experience with distributed systems tooling - Kafka, event-driven architectures, or working with Postgres alongside SQL Server.
• Front-end experience with Angular and/or React/Next.js .
• You've helped establish agent-friendly engineering practices: writing repo instructions that AI tools can follow, breaking work into agent-sized tasks, setting up CI guardrails for AI-generated code, feature flags, and canary deployments - any part of the progressive delivery toolkit.
• Background in regulated domains (healthcare, fintech, payments).
